Subject: [PATCH 00/16] Networking drivers refcount conversions
Date: Tue, 28 Mar 2017 08:56:27 +0000	[thread overview]
Message-ID: <1490691403-4016-1-git-send-email-elena.reshetova@intel.com> (raw)

This series, for various different networking drivers, replaces atomic_t reference
counters with the new refcount_t type and API (see include/linux/refcount.h).
By doing this we prevent intentional or accidental
underflows or overflows that can led to use-after-free vulnerabilities.

The below patches are fully independent and can be cherry-picked separately.
Since we convert all kernel subsystems in the same fashion, resulting
in about 300 patches, we have to group them for sending at least in some
fashion to be manageable. Please excuse the long cc list.

If there are no objections to these patches, please take them
through the relevant trees.
